New system-driven bioremediation of polluted habitats and environment (NYMPHE)
PartnerEuropean Comission
Biological organisms, including the smallest, can play a big role in restoring polluted environments. They remove or neutralise an environmental pollutant from soil or water in a process called bioremediation. The EU-funded Nymphe project will take this process to a new level. Specifically, it will develop bioremediation/revitalisation strategie...Recovery and separation of platinum group metals and rare earth elements from spent automotive catalytic converters (PlatILPlus)
CoordinatorFundação para a Ciência e a Tecnologia
PlatILPlus is an FCT-funded research project that aims to develop eco-friendly yet readily applicable methodologies for the valorization of Spent Automotive Catalytic Converters (SACC) through hydrometallurgical processes. The project focuses on the recovery and separation of Platinum Group Metals (PGM) and Rare Earth Elements (REE) to ...Publications
